I often remember tunes that I learned over 30 years ago better than tunes learned more recently.
There are some researchers who have extensively studied the topic brought up by the OP: how frequently does one need to rehearse a memory in order to maintain that memory. There are some variables, including variation among individuals. What is generally true for everyone though is that the more complex information is, the more it must be rehearsed in order to be memorized. That’s kind of a no-brainer. In general, information must be rehearsed frequently until it is mastered, and then the frequency to maintain the memory can taper off to a certain point.
